Description

  • The invention relates to a plastic container consisting of two container parts which are connected to one another in an opening region.
  • A container of this type is known from DE 201 05 030 U1 of the same applicant. The container described serves to store liquids and consists of at least two separately manufactured and largely identical container parts. Each container part includes an upper and a lower flow nozzle having an aperture. The two container parts are connected to one another in the region of the upper flow nozzle as well as in the region of the lower flow nozzle. Further, the container parts include stiffening corrugations for increasing stability.
  • Such a container can be used for collecting rainwater or waste water and should be suitable for underground storage. Known containers have a spherical, cylindrical or rectangular geometry. For rectangular containers, generally a width which is small compared with the length is chosen in order to withstand soil loads.
  • In order to obtain a large volume, the height of the container must then be chosen high, this requiring a high mounting depth. For reasons of soil quality, such as in the case of stony soils or given the presence of ground water, it is often necessary to keep the mounting depth as low as possible.
  • The object of the invention is to provide a plastic container which has a high capacity and, at the same time, is suitable for underground use and has a high stability.
  • This object is solved by the features of claim 1. Advantageous developments are specified in the dependent claims.
  • According to the invention, the already described principle is maintained according to which the container is assembled of two container parts. In this way, the container parts can be manufactured with the aid of relatively small blowing molds and can be transported well. Each container part has a single connection frame which includes the connection opening. At least one connection frame includes a support device which extends in the vertical direction. As a result, the entire container is supported in the region of the interconnected connection frames and the strength is increased in this region. Thus, the container which is assembled of the two container parts has a high dimensional stability, can take high soil loads and can withstand buoyancy forces in the ground water.
  • In one embodiment, the respective connection frame has a circular shape, the outer diameter of which approximately corresponds to the height of the container. As a result, a large opening surface for the exchange of liquid can be provided between the two container parts. Further, with a large diameter of the connection frame the required connection of the two container parts at the place of mounting, for example by means of welding, can be implemented more easily.
  • According to another embodiment, the base area of the container is approximately square. Accordingly, such a container can be easily embedded in the soil of an existing square piece of land. The increased soil loads and buoyancy forces occurring in this connection are absorbed by the supporting device.
  • Embodiments of the invention are explained in the following on the basis of the drawings.
  • FIG. 1 is a perspective view of a first embodiment of the invention.
  • FIG. 2 is a side view of the container illustrated in FIG. 1.
  • FIG. 3 shows a container part having a not yet separated partition wall formed in one piece with the container part.
  • FIG. 4 is a detail from FIG. 3.
  • FIG. 5 is a view of FIG. 3 as viewed from the direction H1.
  • FIG. 6 is a side view of the container in the assembled state.
  • FIG. 7 is a detail from FIG. 6.

  • FIG. 1 shows, in a perspective view, an embodiment of the invention in which a container 10 is assembled of two container parts 12, 14. The two container parts 12, 14 are made of plastic, for example of high-molecular high density polyethylene, and are manufactured by means of blow molding. The first container part 12 has a filling and emptying opening 16. With regard to the rest, the two container parts 12, 14 are identically structured so that each container part 12, 14 can be manufactured by using the same blowing mold. Only for the first container part 12 having a filling neck 18 (see FIG. 2), a mold insert is placed into the blowing mold.
  • FIG. 2 is a side view of the container 10, the unit for the filling and emptying opening 16 being disassembled; thus in the upper wall 24 only a filling neck 18 can be seen via which the entire container 10 can be filled and emptied.
  • Each container part 12, 14 includes in its circumferential surface stiffening corrugations 20 which serve to stiffen the outer shape of the container 10. These stiffening corrugations 20 are channel-like recesses which are formed in the circumferential surface during the plastic blowing. The stiffening corrugations 20 increase the rigidity of the outer casing so that the soil load and the buoyancy forces occurring due to the ground water are taken into account. The container parts 12, 14 are rounded at their edges and also present the stiffening corrugations 20 mentioned above in their circumferential surface in the lower wall 22 and the upper wall 24.
  • Each container part 12, 14 has a single connection frame 26 or, respectively, 28, along which the two container parts 12, 14 are joined together.

  • FIG. 4 shows that a raised edge 34 is formed along the circumference of the outer casing of the container part 14. At the point 32, the partition wall 30 is then separated along the circumference.
  • FIG. 5 is a view from the direction H1 in FIG. 3. The partition wall 30 includes stiffening ribs 36 in the middle section and through holes 38 on both sides of the stiffening ribs 36. In the region of the stiffening ribs 36 an upper bore 40 and a lower bore 42 are provided in order to allow for an exchange of liquid in the region of the stiffening ribs 36.
  • FIG. 6 shows the container 10 in the assembled state from the side. The container part 14 is assembled to the container part 12 which can only be seen partly, the partition wall 30 belonging to the container part 14 and a partition wall 44 belonging to the container part 12 facing each other. The detail Y is illustrated in more detail as a cross-section in a ratio of 1:4 in FIG. 7. The partition wall 30 illustrated in FIGS. 3, 4, and 5 has been separated along the circumference at the point 32 and has been inserted into the thus created opening of the container part 14 after being turned by 180°. Something similar is carried out for the container part 12 with the partition wall 44. Thus, the two container parts 12, 14 with their partition walls 30, 44 are facing one another. In the region of the raised edge 34 of the container part 14 and a respective raised edge 46 of the container part 12 a circumferential welding with the melting stock 48 is carried out, while at the same time the outer casing of the container parts 12, 14 as well as the appertaining partition walls 44, 30 are joined to one another. The partition walls 30, 44 include the ribs 36 illustrated in FIG. 5 and form the support device for the absorption of vertical forces. The connection frames 28, 26 of the container parts 14, 12, which are illustrated in FIG. 2, are formed in this embodiment by the end faces of the open container parts 14, 12 and the end faces of the partition walls 30 and 44.
  • FIGS. 8 to 12 show another embodiment of the invention in which the facing connection frames 26, 28 of the container parts 12, 14 likewise include a support device. Identical parts are denoted by identical reference characters.
  • On the left-hand side of FIG. 8, a front view of the connection frame 28 is shown, which has two sections 50, 52 as a connection opening. The illustration on the left-hand side is a view as seen from the direction H2 of the side view illustrated on the right-hand side.
